For better and for worse, Avengers: Age of Ultron often played like a two-and-a-half-hour commercial for the Marvel Cinematic Universe. Between the introduction of Ultron, Vision, Scarlet Witch, and Quicksilver, the Easter egg-filled Thor dream sequence, and the Thanos/Infinity Stones mid-credits scene, you almost need to take a course in all things Marvel in order to keep up with all the relationships and references. But since that course isn't readily available yet, graphic designer Hugo A. Sanchez has created a crash course in the form of an amazing Avengers: Age of Ultron infographic.

This infographic has it all, from in-depth descriptions of the relationships between the characters to what the heck was going on with Vibranium. There's also a handy explanation of the Infinity Stones, including which movies each stone has appeared in so far, demonstrating the connections between Age of Ultron/Infinity War and seemingly unrelated franchises like Guardians of the Galaxy.
